Currently it's the year 2000.

You and Huening Kai are bestfriends since childhood, you two hang out together, go to school together, currently highschoolers.

Today while you were walking towards school, you saw Huening Kai

Huening Kai: “Yo check out my new denim jacket” he shows off. Then suddenly there was sound coming from the bushes. You both got curious and decided to see what's inside

Huening Kai: “Huh? What is this?” he says in confusion and shows you a small device with a clock on top with both the past and future years. It is a time machine
